SPECIFICATION forming part of Letters Patent No. 354,741., datedDecember 21, 1886.

Application filed July 22, 1886. Serial No. 208,710. (No model.) I

To aZZ whom it may concern.-

Be it known that I, J QHN SABOLD, a citizen of the United States,residing at Little Oley, in the county of Berks and State of Pennsyl-Vania, have invented certain new and useful Improvements inIn'got-Molds, of which the following is a specification.

My invention relates to a mold for casting metal into ingots, and hasfor its object to pro- IO vide an improved sectional mold provided withspecial clamps, as hereinafter specified.

In the accompanying drawings, which illustrate the invention, Figure 1is a front broad side view of the mold and clamps. Fig. 2 is 1 an edgeor narrow side view of the mold and clamps. Fig. 3 is an end view of themold and clamps, showing the two mold-sections ready for filling. Fig.4. is a partial end view of the two mold-sections, showing them loosenedor separated, and also showing a side view of the guide-tongues. Fig. 5is aninner side and end v ew of one of the clamp-plates. Fig. 6 is aview of the eccentric tightening-shaft. 4

The letter A designates one section, and B the other, of a metal mold.These two sectrons unite at the narrow sides, which are opposite, andsaid sections are separable at the unitlug-edges c on said narrow sides.An impor tant feature is the straight groove 0 in the conironting facesof the said uniting-edges. ThlS groove 0' extends along the entirelength of the uniting-edges, and when the edges of the two sections arein contact the grooves c are colncident and form a bore or passage, as 35 Shown in Fig. 3.

When the mold is being prepared for the molten metal,this bore orpassage is to be filled and packed with sand, clay, 'or any othersuitable packing, whereby the joint at the uniting-edge will be madeimpervious to the passage of the molten metal.

The shape of the interior of the moldis shown in Fig. 3. The interiorbroad sides, d, are smooth, flat, and parallel with each other, and thenarrow sides a are a little concave, or, in other words, commencing ateach broad side,

they spread or flare slightly toward the center unitingedge, c. Thisshape of the interior, it W111 be seen, facilitates the release ordischarge of the ingot upon the two sections A B being loosened orunclamped.

Each outer corner of the two mold-sections is beveled, as at g, and twoclamp-plates, H H, are employed on the narrow sides-one opposite theother-to bind the sections. Each 5 clamp-plate has two beveled flanges,g, and these flanges areon opposite edges and extend parallel with eachother. Each beveled flan ge g is in contact with an outer beveledcorner, 9, and

the flanges of each plate bear against the outer 6o corners of differentmold-sections. It will thus be seen that when the two clamp-plates HHare drawn or pressed toward each other the effect of the beveledflanges is to bind the two moldsections A B together. To facilitate thebeveled flanges in being pressed upon,or against the beveled corners gin case they become warped by heat, said beveled corners are providedwith outaways h, (see Figs. 1 and 2,) which are spaced apart to leavebearings h, which latter only come in contact with the beveled flanges.

In order to guide the two sections A B,whe n v bringing them together,so they .will have the proper relative position, I provide the narrow 5sides of the sections with a stop-block, f, and a tapered tongue, f, thestop-block being on one section and the tapered tongue on the othersection. Thes'hape of the stop-block and tapered tongue is shown in thedrawings; but this shape may vary. In addition to the function alreadyspecified as performed by the stock-block and tongue, these parts are soar ranged and combined with respect to the clampplates H H as to performanother function, 8

which will now be described. A block, f, and

tongue f, which for the present purpose may be termedlaterally-projectinglugs, are secured to each narrow side of themold-sections both at the top and bottom thereof, as shown 0 in Figs. 2and 3, and the clamp-plates H H are applied on the narrow sides betweenthe said top and bottom lugs. This construction of laterally-projectinglugs f f and clampplates allows of the clamp-plates beingloosened 5 andthe mold-sections to partlyseparate, as they must when the ingot isabout to be discharged from the mold, and at the same time prevents theentire separation of the mold-sections from the clamp-plates, which is ade- ICO sideratum, from the fact that the entire mold apparatus hereshown is designed to be lifted so as to discharge the ingot. In. otherwords, the mold is lifted from the ingot.

To provide for'lifting the mold, loops or eyes 1- are attached to eachsection both at the top and bottom. By this means themold can bereversed or placed upside down and lifted from either end.

The two clamp-platesH H are connected and drawn together by a deviceconsisting of the rods L and eccentric tightening-shaft m. Oneclamp-plate has two eccentric or crankshaped shafts, m, (see especiallyFig. 6,) which partly turn in bearings n. This shaft m has at each end awrist, k, and at the center a lever, 0. Each wrist khas pivoted to it arod, L, which extends across the mold-side and corn nects in a suitablemanner with the other clamp-plate. By this arrangement of parts theeccentric shaft m may, by grasping the lever 0, be partly turned oneway.say up--to loosen the two clamps, and turned down to tighten them,as will be readily understood.

Each rod L may be provided with a spiral spring, 1;,where it isconnected with one clampplate, in order to give some elasticity to thedraw on the two plates, thereby to allow for the expansion of the heatedparts due to the molten metal. The construction of the spring part isshown in Fig. 1. One clampplate has on each side two lugs, g, each ofwhich has a hole forthe passage of a rod, L, and also has a recess, 8. Aspiral spring, 1), occupies the said recess, and the rod L passesthrough the hole in the lug and the spiral spring, and a nut, 15, on theend of the rod bears on said spring. The rod L is also provided with acollar, u, rigidly fixed to it. When the clamp-plates are drawn tight,this collar has position near the lug q, as seen in Fig. 1. When theclamp-plates are loosened by turning the eccentric shaft one way, thecollars u are forced up against the lugs q, thereby forcing the saidplates asunder.

Having described my invention, I claim and desire to secure by LettersPatent of the United States- 1. In an open-topped mold for ingots, thecombination of two mold-sections separable on opposite sides of theinold and having outer beveled corners, two clamp-plates, each providedwith two beveled flanges, and each plate having each of its said flangesbearing against the outer corners of different mold-sections, and rodsto connect and draw the clamp-plates together, as set forth.

2. In an open-topped mold for ingots, the combination of twomold-sections separable on opposite sides of the mold and having outerbeveled corners provided with cutaways h, spaced apart, and bearings hbetween the cutaways, two clamp-plates, each provided with two beveledflanges, and each plate havingeach of its said flanges bearing againstthe outer corners of different mold-sections, and means to draw theclamp plates together, as 5 set forth. v

3. In an open-topped mold for ingots, the combination of twomold-sections separable on opposite sides ofthe mold and having outerbeveled corners and provided on the sepa- 7 rable sides, at the top,with a laterallyprojecting lug, two clan1pplates, each provided with twobeveled flanges, and each plate having each of its said flanges bearingagainst the outer corners of difl'erentflmold-sections and applied belowthe said laterally-projecting lugs, and rods to connect theclamp-plates, as set forth.

4. In an open-topped mold for ingots, the combination of twomold-sections separable on 30 opposite sides of the mold and havingouter beveled corners, two clamp-plates, each provided with two beveledflanges, and each plate having each of its said flanges bearing againstthe outer corners of different mold-sections, 5 rods to connect and drawthe clamp'plates together, and eccentric tightening-shaftsm, assetforth.

5. In an open-topped mold for ingots, the combination of twomold-sections separable on 9 oppositesides of the mold and havingbeveled corners, two clamp-plates, each provided with two beveledflanges, and each plate having each of its said flanges bearing againstthe outer corners of difl'erent mold-sections, rods to connect and drawthe clamp-plates together, and a spring, 1, bearing on each connecting-4 rod, as set forth.

In testimony whereof I affix my signature in the presence of twowitnesses. I
